1st things, glad I found this board. I have an 1984 chevy truck 1/2 ton. From what I have been reading this is the last yr chevy put in an inline six. After 120,000 miles the old 250 quit on me (distributor rotor not turning). Anyways till I can find out why, Can I drop a 250 from a 67 Nova in its place. Everything looks good, motor mounts same place, need to add a few things, but It shoudn't have changed that much. Maybe I might even get more horsepwr. Let me know what you think, and thanks.
